H!Fiber Gigabit PCIe NIC with Intel 82573 Chip, 1Gb Network Card Compare to Intel 82573 NIC, Single RJ45 Port, PCI Express X1, Ethernet Card with Low Profile for Windows/Windows Server/Linux

I've had no issues; works great. The low-profile bracket attaches easily, and fits low-profile cases, and i do get close to the full 1 Gbps speed during a large file copy. Not bad for $60.The last one got fried in a lightning strike that happened nearby; even behind a UPS. I guess the EMP on the network cables was too much for it.

I'm using a pair of these Gigabit Dual NIC with Intel 82576 Chip on OpenBSD. Worked OOB. It's been running for about a month now. I've had no trouble getting ~1gbps saturation on these cards between machines tested with iperf or through the internet with various speed test sites.

Our Dell XPS 8930 at church that we use for streaming has the Intel "killer" ethernet E2500 chipset in it. Worked good for a long time, but then all of the sudden it would start dropping out during a service. It would disconnect for a few seconds, then reconnect. It would do it quite often. Tried updating the drivers and trying other tweaks found with net searches but no luck.We switched to wifi but that was causing issues too, the video would stutter or freeze from time to time. Probably because too many devices were connected to it?So decided to try add-on card in the computer. The X4 slot was being used for a video capture card and the X16 for a video card. It has 2 X1 slots but I think the video card covers one of them.After the fiasco with the E2500 was hesitant to go Intel again but the I210 chipset gets good reviews so got this one. Thankfully was able to squeeze this into the open X1 slot and so far so good, our streaming connection appears to be solid now and speedtest is reporting 200/200 which is what our internet service is. Even changed the settings in OBS to get a better picture and it handled it like a champ.

Fast and absolutely compatible with my older motherboards.

Machine goes into power cycling and will not post with this card installed. Motherboard is a Gigabyte X299 Aorus Master. Without this card it operates properly. Sad that there is such a short return window for a non-working product.

Worked in my Nuc9 Extreme's like a charm... unlike my first attempt... wish 2.5 or 10Gb Base-T were affordable like this product is.

Works great.. no problems..

This is a review of four related products purchased here on Amazon.1. Klein Tools VDV826-703 Pass-Thru™ Modular Data Plug, CAT6, 50-Pack (ASIN B076PRM7W8)2. Klein Tools VDV226-005 Compact Pass-Thru™ Modular Crimper (ASIN B07R3GK9FQ)3. Soft Plastic Ethernet RJ45 Cable Connector Boots by Copapa (ASIN B07219KGC4)4. H!Fiber 1Gbe Ethernet Network Adapter (ASIN B074PPRQQK)I’m using CAT 6 UTP (23 AWG) that I bought from a local home center.1. I found the Klein Tools VDV826-703 Pass-Thru™ Modular Data Plug, (CAT6, 50-Pack) to be easy to use. This is my first-time using pass-thru connectors, and I have mixed feelings, but that’s not what this is about. The 23 AWG wires fit in snuggly but did require a bit of convincing to pass thru. They are more expensive than some others that are available, but I know these will work perfectly, especially with a same brand crimper.2. The Klein Tools VDV226-005 Compact Pass-Thru™ Modular Crimper did its job flawlessly. The insulation is held tightly in place, the crimp felt secure, and the pass-thru wires were cut perfectly flush. I still need to try this with cheap plugs, to see if they are cut just as flush, but these work great with their own.3. While I don’t usually use boots, I decided to give them a shot as they make the wires look more “finished”. I purchased the blue Soft Plastic Ethernet RJ45 Cable Connector Boots by Copapa. While they didn’t cost much, they were very soft and fit okay. I wish they were a little tighter around the wire, but that can vary from brand to brand. Overall, I’m happy with them.4. Once the cables were completed, I plugged them into a H!Fiber NIC (Intel I350-T4 chipset). They all fit nicely together, even with the boots. That network card is not the V2, and that was expected. The V2s are harder to find and there are no performance differences. The revision was made to fix a slight power surge during power-on. The network card performed flawlessly with pfSense and I was able to configure two LAGGs with LACP support. One to a Cisco managed switch, and the other to my cable modem (SB8200) but I’ll save those for a different review. This card is working perfectly.
